The servo-motor lift replaces manual pendulum raising, which removes a major source of human variation. It brings the pendulum to the exact same starting angle for every test, with no overshoot and no gradual drift. Because the absorbed energy depends directly on the pendulum’s starting height, this consistent lift is a key factor in repeatable results.

The motor moves smoothly, without jerks or uneven acceleration, so the potential energy at the starting point is always the same. Once the angle is reached, the electromagnetic lock holds the pendulum still, ensuring the release happens under identical conditions from test to test.

This automation is especially valuable in high-volume labs, where manual lifting would introduce fatigue and increasing variation across the shift. By keeping every cycle uniform, the servo-motor system helps maintain accuracy at all energy levels, including demanding tests near 750 J.
